A year after New York City went into lockdown, COVID-19 has claimed the lives of more than 30,000 of its residents. The tragedy’s scale has made it difficult to comprehend the private griefs so many of us have experienced: the million heartbreaks of lost friends, lost livelihoods, lost neighborhood fixtures, lost senses of belonging. Instead of proposing a grand permanent memorial, we asked a wide range of New Yorkers about the moments from the pandemic that stood out to them and how they would want those experiences to be commemorated. In response, a selection of architects and artists translated those clients’ memories into proposals for temporary installations. We imposed no budget limit and no restrictions: The result could be a sculpture, a mural, a pavilion, a song — anything that could become part of the streetscape for a while. Presented here is one of 15 concepts submitted by architects, designers, artists, and composers; the rest will appear over the course of this week.
